The Model 455 dispensing valve is a pneumatically operated, normally closed pinch valve with a disposable fluid path. It was designed to dispense materials with extreme precision. The valve’s micrometer control feature allows users to precisely adjust the material flow, ensuring that materials are dispensed consistently and accurately.

This pneumatic, normally closed needle valve is designed to deliver precise dots or very fine beads of low- to high-viscosity fluids. The valve’s stroke adjustment allows for fine-tuning of the dispense volume, ensuring precise and consistent deposits. Air pressure through the valve retracts the needle assembly from the seat allowing fluid to flow from the valve fluid inlet to the dispensing tip.

The Model 775 is a pneumatically operated spool valve that is designed to accurately dispense a variety of fluids. The valve’s accuracy comes from two main features, its suck-back control and adjustable flow control. The suck-back feature greatly increases accuracy and repeatability when dispensing materials. Having control over the amount of suck-back assures consistent, stringless dispensing of tackier materials, and prevents droplets from remaining on the dispense nozzle when using lower viscosity materials.

The Model 826 is a pneumatically operated, normally closed pinch valve. This dispense valve dispenses a wide variety of materials, and is specifically designed to dispense thicker, stringy materials with ease. The valve is highly precise and obtains its precision from lockable controls that facilitate the adjustment of three critical parameters: the flow rate through the valve, the amount of tube closure, and suck-back.

The Model 828 normally open disposable fluid path valve is designed to provide larger flow rates while still maintaining precise control over material flow rate. This dual-piston pinch valve can be used with many materials and features a suck-back control so it can handle stringy and tacky materials with no mess.

The Model 830 normally closed disposable fluid path valve is designed to provide larger flow rates while still maintaining precise control. This dual-piston pinch valve can be used with many materials and features a suck-back control to handle stringy and tacky materials with no mess.
